What 95721 covers
Code 95721 represents a neurologist’s or other qualified health care professional’s review and interpretation of a prolonged EEG recording, followed by a diagnostic report. It applies when the recording lasts more than 36 but less than 60 hours and has no synchronized video. Such studies may evaluate recurrent spells, suspected seizures, or altered mental status when a brief EEG is insufficient, in hospital or ambulatory monitoring settings. The service is the professional analysis and report, rather than electrode application or technologist acquisition work.
Select the code from the recording duration and whether video was captured. Documentation should support the recording’s dates and times, total duration, lack of video, findings, and professional interpretation. CMS assigns work and practice-expense relative values to this service; the record should substantiate the professional work for the reported study.

95721 billing questions
When is 95721 selected instead of 95722?
Use 95721 for a recording over 36 but under 60 hours without video. Use 95722 for the same duration when video accompanies the EEG.
Does the duration mean physician reading time?
No. The duration refers to the EEG recording, not the time spent reviewing it or preparing the report.
Is 95721 the EEG acquisition service?
No. It represents the physician or qualified health care professional’s review, interpretation, and report. EEG acquisition and monitoring are represented by distinct technical-service codes when applicable.
What documentation supports reporting 95721?
Document the recording’s total duration, that video was not used, and the professional’s interpretation and findings. The record should support a duration over 36 but under 60 hours.
